Abstract

Sesame (Sesamum indicum L.) has been cultivated since ancient times as oilseed crop in the hotter and drier parts of Africa and Asia. In Nigeria, low yield is obtained as a result of poor agronomic practices among others, discourage growers. Field experiments were carried out to evaluate the agronomic characters of Sesame grown at varying levels of NPK fertilizer and row spacing. The field trials were conducted in 2009 and 2010 rainy seasons at the teaching and research farm of the Departments of Crop Production and Horticulture, Modibbo Adama University of Technology, Yola. The treatments consisted of three row spacings (60 x 15cm, 60 x 10cm and 75 x 10cm) and three NPK rates (200, 300 and 400 kgha) which was was laid out in a split plot design replicated three times with plot size 3m x 2m. Parameters measured include establishment count at two weeks after sowing (2WAS), number of primary and secondary branches, days to 50% flowering, length of capsule, number of capsule per plant, 1000 –seed weight and yield per hectare (kgha­-1). Data collected were subjected to analysis of variance (Anova) and means were separated using least significant different (LSD). Results obtained showed significant effects of row spacing and NPK rates on days to 50% flowering, , number of seed per capsule, length of capsule as well as seed yield/ha. The application of 200kgha and spacing of 75cm x 10cm resulted in higher seed yield/ha.

Key words: Agronomic characters, Sesame, row spacing, fertilizer, yield
